Software and Firmware difference

Differentiating between Software and hardware is very easy as the physical part is the hardware, whereas the part which is not physical, such as the processor, is the Software. But the difficulty arises when differentiation has to be done in something such as Software and Firmware.

Software is a set of instructions that helps and guides the user. It provides data or programs that are necessary to execute the tasks on the computer. It is also known as a program that generally runs on a device. It is considered the variable part of the device.

Firmware is a type of software that falls under the category of System Software, which is used to coordinate the hardware with the Software and therefore makes the hardware work. From the TV remotes to the Mobile Phone, everything has Firmware in it.

 Additional details:

Firmware refers to the software that is permanently programmed into a hardware device. It is a type of software that provides the instructions and control necessary for the device to function properly. Firmware is often stored in non-volatile memory components like ROM (Read-Only Memory), flash memory, or EEPROM (Electrically Erasable Programmable Read-Only Memory).

Here are some key points about firmware:

  1. Embedded Software: Firmware is typically embedded directly into hardware components, such as micro controllers, chips, or devices like smartphones, printers, routers, and more. It provides low-level control over the hardware and allows the device to perform its specific functions.

  2. Permanence: Unlike regular software that can be easily updated or changed, firmware is designed to be more permanent. While it is possible to update firmware in many cases, the process can be more complex and carries some risks. Firmware updates are often used to fix bugs, improve performance, or add new features to the hardware.

  3. Initialization and Control: Firmware is responsible for initializing hardware components when a device is powered on. It sets up the device's basic configuration, manages communication between hardware components, and ensures that the device operates as intended.

  4. Device Functionality: Firmware provides the fundamental software layer that allows a hardware device to carry out its intended functions. For example, the firmware in a digital camera controls the image sensor, autofocus mechanisms, and other camera-specific features.

  5. Security and Stability: Firmware plays a role in device security and stability. Vulnerabilities in firmware can potentially be exploited by malicious actors, leading to security breaches. Regular firmware updates can help address security vulnerabilities and improve the overall stability of the device.

  6. Bootloader: Many devices have a component called a bootloader, which is responsible for loading the firmware into memory and starting the device. The bootloader is often a small piece of firmware that runs when the device is powered on.

Overall, firmware is a crucial aspect of modern hardware devices, providing the foundational software layer that enables them to function, communicate, and interact with users and other devices.

AGILE EPICS

Image
 Introduction: An agile epic is a body of work that can be broken down into specific tasks (called user stories) based on the needs/requests of customers or end-users. Epics are an important practice for  agile  and  DevOps  teams. Epics are a helpful way to organize your work and to create a hierarchy. The idea is to break work down into shippable pieces so that large projects can actually get done and you can continue to ship value to your customers on a regular basis. Epics help teams break their work down, while continuing to work towards a bigger goal. What is an agile epic? An epic is a large body of work that can be broken down into a number of smaller  stories , or sometimes called “Issues” in Jira. Epics often encompass multiple teams, on multiple projects, and can even be tracked on multiple boards. Epics are almost always delivered over a set of sprints. As a team learns more about an epic through development and customer feedback, user stories w...

Agile: Scrum Frame work

   If you are just getting started, think of Scrum as a way to get work done as a team in small pieces at a time, with continuous experimentation and feedback loops along the way to learn and improve as you go. Scrum helps people and teams deliver value incrementally in a collaborative way. As an agile framework , Scrum provides just enough structure for people and teams to integrate into how they work, while adding the right practices to optimize for their specific needs.   You may be thinking, that sounds great! But, how do I get started? So, why is it called Scrum? People often ask, “Is Scrum an acronym for something?” and the answer is no. It is actually inspired by a scrum in the sport of rugby. In rugby, the team comes together in what they call a scrum to work together to move the ball forward. In this context, Scrum is where the team comes together to move the product forward.  Scrum Frame work: There are accountabilities (Roles), events and ...
